Kanye's Bound 2 Video features fiancé Kim Kardashian

Kanye West didn't have to look far for a costar to ride shotgun with him in the music video for his new song "Bound 2": fiancé Kim Kardashian, who helps turn up the heat in the road-trip-themed clip.

In the video, which the rapper debuted Tuesday on The Ellen DeGeneres Show, West, 36, and Kardashian, 33, hop on a motorcycle together while vistas of landscapes and all sorts of natural scenery whiz by behind them.

But it's the action on the motorcycle that's sure to grab everyone's attention, as Yeezus and a topless Kardashian bump and grind along to the track, which proffers: "I know you're tired of lovin', of lovin', with to nobody to love.'
